Welding cart with cable management system

ABSTRACT

A welding cart with a cable management system may include a frame, a shelf adapted to support a welding machine, a plurality of upright members, a plurality of wheels supporting the cart, one or more pairs of holders disposed on one or more sides of the cart, and a removable bar that may be releasably secured to the one or more pairs of holders. The bar may be releasably secured to the holders via a pin-and-hole mechanism and may have a hook adapated to hold welding equipment such as cables. The bar may be releasably secured to a first pair of holders disposed on a side of the cart or a second pair of holders disposed on another side of the cart. This system provides additional, easily accessible storage space for welding tools and accessories while still being compatible with a wide variety of portable welding machines.

BACKGROUND

Welding

Welding is the process of joining two or more metals by heating the surfaces of the metals to the point of melting. Welding has many applications and is used in many industries such as the automotive industry, construction industry, and manufacturing industry. For example, in the automotive industry, welding can be used to bond heat shields, exhaust systems, chassis, and hydraulic lines. In the construction industry, welding can be used to form connections in buildings bridges, and other infrastructure. In the manufacturing industry, welding can be used to form furniture pieces such as office desks and file cabinets, HVAC units such as heating, ventilation, and air conditioning units, and frames for farm equipment.

There are many types of welding processes, the main types being MIG welding, TIG welding, arc welding, and flux core arc welding. Each of these welding processes produces different weld properties and, as such, each welding process is best suited for certain applications. For example, TIG welding produces high quality, precise welds and can be used for welding a variety of metals. MIG welding, on the other hand, uses wire as a filler to produce cleaner welds better suited for metals such as steel and aluminum.

Welding Machines

Different welding processes require different welding machines. For example, MIG and flux welding requires a MIG-type welding machine and TIG welding requires a TIG-type welding machine. Examples of portable MIG welding machines include the VULCAN OMNIPRO 220, MILLER MULTIMATIC 255, and LINCOLN ELECTRIC POWER MIG 210.

Because wire feed (MIG) welding uses wire as a filler to join two metals, MIG welding machines must continuously feed wire onto the workpiece during welding. As such, MIG welding machines house a replaceable spool of wire inside the machine. When the wire is depleted, the wire spool must be replaced with a new one. In most MIG machines, the wire spool can be accessed by lifting a door on the side of the machine. The side on which the door is located may differ between welding machines. The door therefore may be disposed on the right side of one welding machine and the left side of another. For example, the door of the VULCAN OMNIPRO 220 is located on the right side of the welding machine while the door of the MILLER ELECTRIC MULTIMATIC 255 is located on the left side.

Wire feed welding machines may come in varying sizes. Some welding machines are small enough to be considered portable. While portable machines are relatively smaller than larger industrial welding machines, they still may be too large and heavy for one person to conveniently transport. As such, a welding cart is usually needed to hold and transport portable welding machines.

Welding Carts

Many conventional welding carts have a surface for supporting a welding machine, but lack sufficient storage space for welding tools and accessories, such as helmets, torches, cables, leads, gas hoses, and replacement wire spools. Further, any limited storage space that is available may not be easily accessible.

Welding cables, leads, and gas hoses (collectively called “cables”) can be particularly difficult to store because they are thick and long. For example, a welding cable may be between about 5 feet and about 25 feet long. Typically, when the cables are not in use, they are wrapped around the welding machine, hung over the handles of welding cart, or set on the bottom upper shelf of welding cart. These cable storage methods can be difficult, disorganized, and unsecure. As an alternative, cables may also be stored on a wall or other separate surface. This method makes shutdown and startup more difficult and time consuming because the cables must be attached and detached from the welding machine with every use.

SUMMARY

A welding cart with a cable management system may include an upper shelf, a lower shelf disposed below the upper shelf, a frame, a plurality of upright members, a plurality of wheels supporting the cart, and a cable management system.

The cable management system may include a first pair of holders disposed on a side of the cart. The first pair of holders may further include a mounting arm and a support arm, and the support arm may further include a hole adapted to receive a pin on a bar.

The cable management system may further include a second pair of holders disposed on a side of the cart. The second pair of holders may be disposed on a side of the cart opposite the first pair of holders. The second pair of holders may further include a mounting arm and a support arm, and the support arm may further include a hole adapted to receive a pin on a bar.

The cable management system may further include a bar. The bar may include a hook. The hook may have a prong adapted for securing cables and other tools on the hook. The bar may further include a pin adapted to fit into a hole in the support arm of a holder. The bar may include two pins disposed on opposite ends of the bar and each adapted to fit into a corresponding hole in adjacent holders.

The bar may be releasably secured to the first pair of holders or the second pair of holders. Whether the bar is releasably secured to the first pair of holders or the second pair of holders may depend on the specific needs of the user or the configuration of the welding machine. Specifically, the bar may be releasably secured to a pair of holders disposed on the side of the cart opposite the door of the welding machine.

For example, if the first pair of holders is disposed on the same side of the cart as the door of the welding machine, the bar may be placed on the second pair of holders disposed on the opposite side of the cart. Accordingly, the space in front of the door may remain clear such that the door may be freely opened and closed. If, on the other hand, the second pair of holders is disposed on the same side of the cart as the door of the welding machine, the bar may be placed on the first pair of holders.

Further, the bar may be freely transferred between the first pair of holders and second pair of holders as needed.

This flexibility of the cable management system gives the welding cart increased storage capacity while also allowing the welding cart to be used with various types and configurations of welders.

Other systems, methods, features, and technical advantages of the invention will be, or will become apparent to one with skill in the art, upon examination of the figures and detailed description. It is intended that all such additional systems, methods, features and technical advantages be included within this summary and be protected by the claims.

DETAILED DESCRIPTION OF THE DRAWINGS

1.0 Welding Cart Overview

Referring to the drawings and initially to FIG. 1 , a perspective view of an exemplary welding cart 100 is shown. Welding cart 100 may include a frame, which may further include one or more support frames 200, a lower shelf 300 attached to each support frame 200, an upper shelf 400 attached to each support frame, a plurality of upright members 500 two of which may include a handle 510, a plurality of wheels or casters 610, 620 supporting the cart, and a transferable cable management system 700 that includes a first pair of holders 710 a disposed on a side of the welding cart 100, a second pair of holders 710 b disposed on an opposite side of the welding cart 100, and a bar 720 releasably secured to either the first pair of holders 710 a or the second pair of holders 710 b, the bar having at least one hook 730.

Referring to FIG. 6 , in operation, upper shelf 400 of welding cart 100 may be used to support a welding machine 800. Welding machine 800 may be a portable wire feed welding machine which feeds wire through a cable and out a nozzle located at the tip of a torch. A wire spool may be disposed on spindle located inside welding machine 800 and accessed by lifting hinged door 830 disposed on the side of welding machine 800, as shown in FIG. 6 .

When the wire on wire spool is depleted, the wire spool may be replaced—a process that requires opening the welding machine door 830. When replacing the wire spool, door 830 must be pulled outward and upward, and lifted above welding machine 800, as shown in FIG. 6 . Thus, the space in front of door 830 must be clear of any objects during replacement of the wire spool. As described above, the door may be located on different sides of different welding machines.

Welding requires the use of many tools and accessories, such as helmets, cables, leads, hoses, and wire spools. While lower shelf 300 of welding cart 100 may be able to hold some of these objects, additional space may be required. As described above, cables are particularly difficult to store on welding carts because of their length and thickness. A cable management system 700 located on the side of welding cart 100 may provide additional, easily-accessible storage space for welding tools and accessories, such as cables 900.

As further described above, because the door of the welding machine may be located on different sides of different welding machines, a rack fixed on one side of welding cart 100 may limit use of the cart to certain welding machines.

A welding cart may therefore include a cable management system 700 that can be placed on either side of the welding cart 100. The side of the welding cart on which the cable management system 700 is placed may depend on the configuration of the welding machine 800 disposed on the cart 100. For example, if the door 830 is located on one side of the welding machine 800, then the cable management system 700 may be located on an opposite side of the welding cart 100 such that the door 830 of the welding machine 800 may be freely opened.

2.0 Exemplary Frame

The welding cart may include a frame. The frame may be adapted to support a welding machine disposed on an upper shelf. As shown in FIG. 1 , the frame may include one or more support frames 200. For example, as shown in FIG. 1 , the frame may include a pair of support frames 200. Each support frame 200 may have an upper arm 210, a lower arm 220, and a substantially vertical arm 230 that connects one end of upper arm 210 to one end of lower arm 220. The length of upper arm 210 may be substantially equal to the length of lower arm 220, or alternatively, upper arm 210 may be shorter in length than lower arm 220, as shown in FIG. 1 . Each substantially vertical arm 230 may have a height. Each support frame may have one or more additional substantially vertical arms connecting upper arm 210 and lower arm 220 for added stability. For example, a support frame 200 may have two substantially vertical arms connecting the upper arm and lower arm of the support frame such that the support frame forms a rectangular shape.

In one embodiment, the upper arm 210 and lower arm 220 of each support frame 200 may be substantially parallel to one another. Alternatively, as shown in FIG. 1 , upper arm 210 of each support frame 200 may be oblique to corresponding lower arm 210 of each support frame 200.

For example, one or more crossbars may connect both upper arms 210 of support frames 200. Additionally or alternatively, one or more crossbars may connect both substantially vertical s 230 of support frames 200.

The support frames 200 may further include one or more holes through which bolts, axles or other elongated components may be inserted. Each hole in a support frame may pass through a portion of the support frame 200 or may pass entirely through the support frame 200. In one embodiment, the lower arm 210 of each support frame may include a hole. Further, a hole in lower arm 220 of one support frame 200 may align with a hole in lower arm 220 of an opposing support frame 200 such that an axle or other elongated member may be inserted through the holes and connect the support frames 200.
